In the case of the citric acid titration, a known amount of orange juice is measured into an Erlenmeyer flask with an indicator solution containing phenolphthalein (the indicator). Sodium hydroxide, at a known concentration, is then carefully added into the sample until all of the acid has reacted.
In this experiment you will titrate a measured volume of citric acid (C6H8O7) with a solution of NaOH of a known concentration. The acid and the base react with one another according to the equation: C6H8O7 (aq) + 3 NaOH (aq) ® C6H5O7Na3 (aq) + 3 H2O (l) 1:3 ratio in reaction.
2 sty 2014 · Instead of sulfuric acid, this lab involves two different acids: citric acid and ascorbic acid (both are acids, thus each reacts with NaOH). You can determine the TOTAL amount of acid (total moles of H+ = moles of H+ from citric acid + moles of H+ from ascorbic acid) present in a juice sample by titration with NaOH, a strong base. Equation 1
Citric acid (left), Tartaric acid (middle), Malic acid (right) The amount of citric acid in citrus fruit juices can be determined by titration with a standard solution of sodium hydroxide. A standard solution is one whose concentration is accurately known, usually to three significant figures.

15 mar 2021 · Objectives. To determine the amount of citric acid present in fruit juices. Some citrus fruits taste more sour, and therefore are more acidic, than others. It is the purpose of this experiment to determine the total acidity of orange, lemon, grapefruit, white grape or lime juice.
Simple, accurate, and sensitive UPLC-PDA method for citric acid analysis; Utilization of an ACQUITY Premier CSH Phenyl-Hexyl Column to improve the peak shape and sensitivity of citric acid for the analysis of sports and energy drinks for quality control indicators and to to meet product specifications to simplify this
